one i'd never use 2 bit windows in a production env.
second 30g cache is i think way to large even for crappy cooe
i'd think that a 30g cache would be abottle nect itslef sine the system has to
sequentially scan the cache everytime.

Hi All,
In an interesting insight into how Don Burleson performs tuning at the
c.d.o.s newsgroup
(http://groups.google.com/groups?dq=&hl=en&lr=&ie=UTF-8&th=73f606eef5e7e99f)
. Don suggests he has "no problem throwing hardware at crappy code when the
client doesn't want to tune it". He's also basically recommending using AWE
and utilising all available RAM on 32bit windows, whether you need to or
not. I mean, AWE has no disadvantages right ... :)
However, he also makes the claim that "It's not uncommon to see working sets
of frequently-referenced data of for than 30-gig for a large database. AWE
is a great techniques for 32-bit Windows databases and I do it for dozens
of databases every year, ALWAYS with great results."
So my question to you all is how large are your largest buffer caches ? How
many of you have a buffer cache that is 30G+ ? And on 32bit windows ?
Love to know !!
Cheers
Richard
